Dashcam footage shows the dramatic moment police officers finally stopped a bank robber on a Michigan highway after the wanted man stabbed himself behind the wheel.

The video, which was shared with the Kalamazoo Gazette, reveals Michigan State Police trailing Brian Standiford, 49, at low speeds before one of their trucks knocks the side of his car to force him off I-94.

After one failed attempt that sent Standiford's car spinning, the truck knocks him again, forcing him into a snow bank. As police approach, he raises his hands out of the window.

Before the scene captured on video on January 13, Standiford had allegedly robbed an Old National Bank in Portage but was forced to run after a dye pack exploded.

Knock: After Standiford failed to stop after driving over spike strips so the trooper knocked his car, sending him into a snowbank. Officers had feared he would crash in a more populated area

Police spotted him driving his getaway car and following him onto I-94, where they set up spike strips near Exit 60 to Paw Paw.

But after he hit the strips, which deflated his wheels, he continued his slow-moving getaway. Also after hitting the strips, he pulled out a knife and attempted to stab himself in the chest, police said.
